Footnote 3- Acquisitions and Divestitures Acquisitions: 3M makes acquisitions of certain businesses from time to time that are aligned with its strategic intent with respect to, among other factors, growth markets and adjacent product lines or technologies. Goodwill resulting from business combinations is largely attributable to the existing workforce of the acquired businesses and synergies expected to arise after 3Ms acquisition of these businesses. 2019 acquisitions: In February 2019, 3M completed the acquisition of all of the ownership interests of the technology business of M*Modal for $0.7 billion of cash, net of cash acquired, and assumption of $0.3 billion of M*Modals debt.
